- The reactions of atomic nitrogen with S2Cl2 and other sulfur compounds
-
Atomic nitrogen reacts as an electrophilic reagent toward sulfur compounds. Divalent sulfur compounds (H2S, CS2, OCS, S8, S2Cl2, SCl2) yield sulfur-nitrogen compounds. Sulfur compounds containing sulfur atoms with a positive formal charge (SO2, SOCl2) yield no sulfur-nitrogen compounds. The rate law for the reaction of atomic nitrogen with S2Cl2 to form NSCl is similar to that for the S2Cl2-catalyzed nitrogen recombination reaction. Mechanisms are proposed for the latter reactions, assuming that both reactions are first order in S2Cl2.

- Experimental observation of the 16-electron molecules SPN, SNP, and cyclic PSN
-
16-Electron triatomic ring: Novel thiazylidynephosphane (SNP) was produced by either flash vacuum pyrolysis (ca. 1000 °C) or laser photolysis (193 nm) of SP(N3)3. Its photointerconversion to cyclic thiazaphosphirine (cyc-PSN) and thiophosphoryl nitride (SPN) was found in Ar matrix at 16 K. Cyc-PSN is the first experimentally observed 16-electron cyclic triatomic molecule. Copyright

- Infrared spectra of new sulfur-nitrogen species in solid argon
-
New sulfur-nitrogen species were produced in an argon/nitrogen/sulfur vapor microwave discharge, and the reaction products were trapped in solid argon at 12 K. Nitrogen-15 and sulfur-34 isotopic substitutions, concentration variation, photolysis, and changes upon annealing provided a basis for identification and characterization of the new products. A product absorption at 1209.4 cm-1 is identified as the diatomic SN radical. The strongest product absorption at 1225.2 cm-1, which shows a triplet and a doublet pattern with mixed sulfur and mixed nitrogen isotopes, respectively, is assigned to the antisymmetric stretching vibration of the NS2 radical; these isotopic data provide a 153 ± 5° measure of the valence angle in NS2. The less stable NSS isomer absorbs at 1017.1 and 594.6 cm-1 and is converted to NS2 with near-ultraviolet photolysis. An absorption band at 2040.2 cm-1 shows quartet and doublet patterns with mixed nitrogen and sulfur isotopes, respectively, and is assigned to the nitrogen-nitrogen stretching fundamental of N2S. Evidence for higher nitrogen sulfides is also presented.
